W. T. GRAY DRAWING BOARD July 3o, 1935.

Filed May l2, 1934 Patented July 30, 1935 UNITED STATES PMI-:rrrv oFFlcE2 Claims.

This invention relates to a drawing board, particularly useful fordraftsmen, sketchers and artists-whether students or experienced.

An object of my invention is to provide a draw- 5 ing board which -issimple in construction and which will quickly and eectively hold inposition the paper to be drawn upon.

Another object is to provide a drawing board with a novel frame whichserves to clamp the paper in position, the frame being calibrated on allfour sides thereof, so that the workman can quickly and easily draw anobject upon the paper to the proper dimensions.

Other objects, advantages and features of invention may appear from theaccompanying drawing, the subjoined detailed description, and theappended claims.

In the drawing:

Figure 1 is a top plan view of my drawing board.

Figure 2 is a front elevation of the same.

Figure 3 is a transverse sectional View of my drawing board,

Figure 4 is a perspective View of the same with the clamping frame inelevated position.

Referring more particularly to the drawing, the numeral I indicates thebase, preferably made of wood. However, any other suitable material maybe used.

On each side of the base I and extending longitudinally thereof, Iprovide a beading or edging 2, 3. The beading projects above the uppersurface of the base I to serve as a guide for the paper and also toalign the movable frame, as will be further described.

A rectangular frame 4 is hingedly secured to the base I at the upperedge thereof, by means of hinges 5, 5. A fastener 6 on the swinging endof the frame 4 secures said frame to the base l when in loweredposition, as shown in Figures l and 2. The frame 4, when in closedposition, is substantially iush with the upper face of the beading 2, 3,as shown in Figure 3.

The four sides of the frame 4 are calibrated, as shown at 1. Thecalibrations on both sides increase from the top to the bottom, whilethe calibrations on the upper and lower edges of the frame increase fromleft to right. With this arV rangement, lit is possible to quickly andaccurately draw parallel lines on the paper by simply resting a straightedge on corresponding numbers on either the sides of the frame or thetop and bottom thereof. Y

The drawing paper is held on the board by first releasing a catch orfastener 6 and then elevating the frame 4. Paper is then placed on thebase I and is squared by placing one edge of the paper against one ofthe headings 2 or 3. The frame is then lowered and the fastener 6 isengaged, thereby clamping the drawing paper securely in position.

Having described my invention, I claim:

1. A drawing board comprising a base, beading on two sides of the baseand extending upwardly therefrom, a rectangular frame hingely mounted tothev base between the beading, said frame being adapted to t between thebeading and to rest on the base, a catch on the swinging end of theframe, said catch` engaging the base whereby the frame is held tightlyagainst. the base, said frame being calibrated on all four sidesthereof.

2. A drawing board comprising a flat base, a rectangular frame hingedlymounted on one edge of said base, the drawing paper being adapted to beclamped between the frame and the base, fastening means on the swingingend of said frame whereby said frame is secured to the base, and beadingon two sides of the base extending upwardly therefrom, said beadingextending the length of the base, and the frame tting between thebeading when in closed position, said frame being calibrated on all foursides.
